Shaun Draughn

Draughn, a 27-year-old veteran, will have to fight to earn a roster spot behind Isaiah Crowell, Terrence West and Duke Johnson on the running back depth chart. He collected all 10 of his 2014 carries ...

Draughn is attempting to quickly learn the San Diego playbook so that he can be ready to contribute on Sunday against the Jaguars, but he is not expected to make much of an impact yet, the San Diego Union-Tribune reports.

The Chargers are starved for depth at running back after Ryan Mathews and Danny Woodhead succumbed to long-term injuries in the last two weeks, so the addition of Draughn will give the Chargers a needed body behind starter Donald Brown. Draughn, who saw limited usage in two games with the Bears before he was released last week, will likely be worked into the Chargers' game plan slowly as he familiarizes himself with the playbook. It may not be long, however, before he surpasses Brandon Oliver for the top backup spot behind Brown.

After serving as the Chiefs' primary backup running back in 2012, Draughn saw light action in only three games with the Ravens last season, attempting only two carries. He latched on with the Bears on a one-year deal in April, and will compete with Michael Ford and rookies Ka'Deem Carey and Jordan Lynch for the right to back up Matt Forte in the team's ground attack.

2013

Draughn will compete with rookie Knile Davis for the right to be the primary backup to Jamaal Charles.

2012

Draughn will compete with rookie Cyrus Gray for a spot in the running back rotation behind Jamaal Charles and Peyton Hillis. He is more likely to land on the practice squad than he is to earn any significant playing time.
